Under the UN-Decade of Ecosystem Restoration and Bonn Challenge, second-growth forest is promoted as a global solution to climate change, degradation and associated losses of biodiversity and ecosystem services. Second growth is often invaded by alien tree species and understanding how this impacts carbon stock and biodiversity recovery is key for restoration planning. We assessed carbon stock and tree diversity recovery in second growth invaded by two species and non-invaded second growth, with associated edge effects, in the Brazilian Atlantic Forest. Carbon stock recovery in non-invaded forests was threefold lower than in invaded forests. Increasingly isolated, fragmented and deforested areas had low carbon stocks when non-invaded, whereas the opposite was true when invaded. Non-invaded forests recovered threefold to sixfold higher taxonomic, phylogenetic and functional diversity than invaded forest. Higher species turnover and lower nestedness in non-invaded than invaded forests underpinned higher abundance of threatened and endemic species in non-invaded forest. Non-invaded forests presented positive relationships between carbon and biodiversity, whereas in the invaded forests we did not detect any relationship, indicating that more carbon does not equal more biodiversity in landscapes with high vulnerability to invasive acacias. To deliver on combined climate change and biodiversity goals, restoration planning and management must consider biological invasion risk. This article is part of the theme issue 'Understanding forest landscape restoration: reinforcing scientific foundations for the UN Decade on Ecosystem Restoration'.

Diamond Blackfan anemia (DBA) is an autosomal dominant disorder with a heterogeneous clinical presentation which may include macrocytic anemia typically presenting in the first year of life, growth retardation, and congenital malformations in 30%-50% of patients. This phenotypic variability is partially explained by genotype-phenotype correlations, with several ribosomal protein genes implicated in this disorder. Most cases are due to de novo variants, but familial occurrences highlight variable expressivity and reduced penetrance.

Bisphenol F (BPF) is an environmental endocrine disruptor capable of crossing the placental barrier and affecting the growth and development of offspring. Despite its potential impact, systematic research about effects of BPF on the reproductive function of male offspring remains limited. In this study, pregnant female mice were exposed to BPF at doses of 40, 400, and 4000 μg/kg during gestation and lactation, respectively, to evaluate its impact on testicular damage, testosterone levels, and spermatogenesis of male offspring (F1 generation), and further explore the mechanisms using transcriptomics.

The research aimed to evaluate the effects of a commercial blend of phytogenic compounds on the digestibility, antioxidant system, intestinal microbiota, and performance of weaned piglets. Two experiments compared three treatments (diets): control, zinc bacitracin (300 g/t) and blended phytogenic compounds (400 g/t). The first experiment analised of digestibility of the dry matter, organic matter, crude protein, crude energy and metabolizable energy, in addition to blood parameters and gut microbiota in 15 piglets commercial cross-bred, weaned at 28 days of age, castrated males, weighing 9.

Osteosarcoma tissues demonstrated elevated expression of proteins (FDX1 and DLAT) integral to cuproptosis in our preliminary study, indicating the potential effectiveness of anti-tumor strategies predicated on this process. Nevertheless, the overexpression of copper export proteins and the challenge of copper ion penetration may contribute to insufficient local copper ion concentration for inducing cuproptosis. Herein, we engineered a biomimetic copper-elesclomol-polyphenol network for the efficient delivery of copper ions and the copper ionophore elesclomol.

Objective: Women remain a minority of trainees in interventional radiology (IR) since the residency's inception in 2014. Similar phenomena have been observed in other surgical specialties. Our study aims to quantify changes in female trainee representation in integrated IR over a five-year period from the 2018-19 to 2022-23 academic years and to compare with trends in other specialties.
